Researchers Make Significant Breakthrough in Quantum Computing

A group of researchers at the University of Tsukuba has revealed  that the group is currently working on a new process to create coherent lattice waves inside silicon crystals using ultrashort laser pulses.

In the research, the group used theoretical calculations along with experimental results of the scientists from University of Pittsburgh to show that coherent vibrational signals could be maintained inside the samples. The scientists expect that their latest discovery will help to improve the current generations of computers while making significant progressions towards quantum computing.

While modern computer processors have come a long way, they still contain fundamental limitations. First one is basically the physical limit of transistors manufacturers can implement inside a processor. In order to increase the processing power of such chips, we will need to eventually find ways to increase the numbers in the coming years. For instance, even the most powerful computers can struggle to solve complex problems at the moment.

However, physicists think that the quantum computers hold the keys to solve the problems created by limited processing powers of modern computers. In quantum realm, electrons act more like waves than the traditional ways. Most importantly, various components in quantum realm can become entangled at it can be difficult to explain properties effectively. However, in their current research, the team used very short laser pulses to excite electrons inside a silicon crystal. According to the scientists, this would help us to make transition to quantum computers more easily in future.

Prof. Muneaki Hase shared his excitement about the research. He said, “This experiment reveals the underlying quantum mechanical effects governing the coherent vibrations. In this way, the project represents a first step towards affordable consumer quantum computers.”
